PULLEY-BELTER.

SPECIFICATION forming part of Letters Patent No. 346,067, dated July 20,1886.

Application filed January 5, 1886. Serial No. 167,729. (No mod cl.)

To aZZ whom it may concern:

Be it known that I, FRANK'B. RAY, residing at Kansas City, in the countyof Jackson and State of Missouri, and a citizen of the United States,have invented a new and useful Improvement in Pulley-Belters, of whichthe following is a full description, reference being had to theaccompanying drawings, in which- Figure 1 is a side view of a largebcltpulley. Fig. 2, a cross-section of a portion of the pulley; Fig. 3,a broken section showing an under or inside view of a portion of thepulley and the method of attaching my device, and Fig. 4 a modification.

The object of this invention is to construct a pulley-belter which maybe applied to beltpulleys of various sizes and constructions for thepurpose of enabling a single attendant to apply a heavy belt to thepulley or wheel and to attach the belter in such a manner that it may ormay not be detached or taken off, as desired, and also one which can beapplied to a belt pulley or wheel which runs close to some portions ofthe supporting-frame or adjoining machinery; and its nature consists inthe improvements herein after described and claimed as new.

In the drawings, a indicates the rim of a pulley-wheel; I), the spokes;c, the beltcr; d, an engaging slit or notch therein; 0, theattaching-bolt, and f the fastening-screw.

In the form shown with the hooked bolt the device is designed tobeattached to abeltwheel having a center hub and radiating spokes, whichmay be made in any of the various forms known in the constructions ofsuch wheels or large pulleys. The beltcr c is made of metal and formedto project above and below the rim of the wheel, as shown in Fig. 2. Inorder to lock and maintain it in position on the wheel, it is providedwith a groove or notch, (Z, which fits upon the edge of the rim whenmade to fit any particular or special form of wheels. For general usethe slot (1 is made a little wider than the thickness of average rims.

The bolt 0, as shown in Figs. 2 and 3, is formed with a hook or openingat the inner end, so as to engage with one of the spokes of the wheel,and it passes through the lower projection of the beltcr and is providedwith a looking or tightening screw, f. The screwthreadon the outer endof the rod may be made of a considerable length, so that the belter maybe used with wheels having different widths of rim. A second bolt may beprovided with a hook or notch to extend across under the rim of thewheel and engage on the opposite side, as shown by dotted lines at 9,Fig. 2, which will be the more desirable bolt to use, when the beltwheel or pulleyis provided with spokes or arms, which are thin and wide,and also in cases of smaller pulleys, where the connection between the 65 rim and the hub is continuous, with the exception of two or moreholes. This construction furnishes a very simple belter, which is easilyapplied to one side of the pulley, which may be permitted to remain toprevent its running off of the belt, as it has no effect upon the actionof the belt in operation, or it may be taken off if desired. In thisrespect it will be found an improvement over the belters heretofore inuse and also in the further respect that it can be applied to pulleys orwheels running close to the frame-work or other parts of the machinery.

This device will be found exceedingly useful in belting portableengines, thrashing-ma- 8o chines, horse-powers, and in other placeswhere long or heavy belts are used. Its operation will be obvious, asall that is required is that the outer edge of the belt should be placedwithin the reach or grasp of the belter, 8 5 which can be easily donewhen it is in the position shown in Fig. l or in any position in whichthe belt would be out of contact with the wheel when in operation. Then,starting the machinery, it completes the belting of the wheel, and it isobvious that by placing it on the side of the wheel to which the belthas a tendency to run off the device may be allowed to remain to preventthe belt from running off, as it is not heavy enough to affect the op- 95 eration of the wheel. Vhere there is no such tendencythe device may beremoved.

It will be understood that the long or short attaching-bolt will notboth be used at the same time, but that the bolt will be changed from along one to a short one, according to the construction of thepulley-wheel to which The belter I, having the notch (Z adapted to 10engage with the edge of a pulley-rim, in combination with anattaching-bolt, substantially as specified.
